Configure file systems by using NTFS, FAT32,
or FAT.
FAT File allocation table refers to a
disk format, which is a way of organizing the
storage space on a hard disk. The table
organizes information about the files on the
hard disk, representing each one as a chain of
numbers that identifies where each part of a
file is located. The operating system uses it to
look up a file and find which clusters that file
is written to on the hard disk.
FAT16 Supports drives up to 2 gigabytes
in size. Fat16 is the most compatible file
system, not only can all windows versions use it
but many other OS's also.
FAT32 Supports drives of up to 2
terabytes in size. FAT32 also reduces the
cluster size on large drives, freeing up more
space.

NTFS4 New
Technology File System used with win NT 4
provides greater security than FAT, and
better disk compression.
Support for large hard disks, up to 2 terabytes
and as drive size increases, performance with
NTFS doesn't degrade as it does with FAT.
NTFS5
Updated NTFS for windows 2000,NTFS The NTFS file
system is the recommended file system for use
with Windows 2000. NTFS has all of the basic
capabilities of FAT, and it provides the
following advantages over the FAT and FAT 32
file systems:
Better file security with encrypting
file system (EFS)
Better disk compression.
Support for large hard disks, and as
drive size increases, performance with
NTFS doesn't degrade as it does with
FAT.
HPFS High Performance File System is the
file system used with OS/2. Windows NT 3.51
supported partitions formatted with HPFS , but
it did not support formatting new drives as
HPFS. In Windows NT 4.0, the support for HPFS
was eliminated.
